Monitoring system for scouring state of offshore wind power piles

Abstract

The invention provides a monitoring system for scouring state of offshore wind power piles, comprising a broadband high frequency sonar device, a positioning device, a multi-angle adjusting bracket and a main control computer; the broadband high frequency sonar device is used for transmitting broadband or single frequency spectrum sound signal to the seabed, and receiving and pre-processing echo signals of multiple independent channels; the positioning device is used for positioning each pile; the multi-angle adjusting bracket is used for adjusting the spatial position of a transducer and angles of transmitted beams to realize monitoring of several continuous points and angles of the seabed piles; the main control computer is used for sending a setting instruction and a working instructionto the broadband high frequency sonar device, receiving and processing echo data of the broadband high frequency sonar device, displaying and storing the echo data, performing signal analytic processing and fitting according to the echo data, obtaining a curve of water depth changing with time, playing the historical echo data back and determining the scouring corrosion situations of the offshorewind power piles. The invention belongs to the technical field of underwater pile monitoring of offshore wind power, the scouring situations of the piles can be monitored in real time and intuitively, and accurate maintenance information is provided.

Description

technical field [0001] The invention belongs to the technical field of underwater pile monitoring of offshore wind power, and in particular relates to a monitoring system and method for scour state of offshore wind power piles. Background technique [0002] In recent years, my country has made great efforts to develop and build a maritime power, and offshore wind power and offshore oil exploitation have developed rapidly. However, these long-standing piles in the ocean, such as oil drilling rig construction platforms, offshore wind power platforms, and cross-sea bridge piers, will interfere with the flow velocity of the water body, thereby forming vortices near the piles and continuously washing the piles, causing sediment and other pollutants near the piles. The loss of sediment material reduces the strength of the pile, thus affecting the stability and safety of the offshore wind power pile. Therefore, how to effectively monitor the sediment subsidence and exposure of the ...
